As your can tell from the LG 23EA53V-P spec's it is an IPS LED monitor. Where as the LG 23EA53VQ-P is a TFT LED monitor.
Depending on what your use your monitor. An IPS LED monitor will have a better colour gamut/truer colours; where as TFT LED does not by default have good colours (compared to an IPS), but, should have better response time: i.e. IPS ~ 5ms vs. TFT ~2ms, so it might be better for you if you are a FPS gamer.
TFT ?? where can I see that info? because there's a local store where the 23EA53VQ-P is stated as an IPS panel..!!
Here is a portion of the SPECIFICATIONS from the owners manual for the 22/23/24/27EA53VQ-P
"58.4 cm (23 inch) Flat Panel Active matrix-TFT LCD Anti-Glare coating"
Which can be found HERE: http://www.lg.com/hk_en/support-product/lg-23EA53VQ-P#. Scroll down till you see "OWNERS MANUAL", click on "English" for either DjVu or Adobe Reader (I use Adobe Reader). Open the file and under "SPECIFICATIONS" look at the spec's of the 23" version.
